Microscopic derivation of Hubbard parameters for cold atomic gases
H. P. Büchler
We study the exact solution for two atomic particles in an optical lattice interacting via a Feshbach resonance. The analysis includes the influence of all higher bands, as well as…
Polar Molecules with Three-Body Interactions on the Honeycomb Lattice
Lars Bonnes, Hanspeter Büchler, Stefan Wessel
We study the phase diagram of ultra-cold bosonic polar molecules loaded on a two-dimensional optical lattice of hexagonal symmetry controlled by external electric and microwave fie…
A Rydberg Quantum Simulator
Hendrik Weimer, Markus Müller, Igor Lesanovsky +2
Following Feynman and as elaborated on by Lloyd, a universal quantum simulator (QS) is a controlled quantum device which reproduces the dynamics of any other many particle quantum…
Supersolid phase with cold polar molecules on a triangular lattice
L. Pollet, J. D. Picon, H. P. Buechler +1
We study a system of heteronuclear molecules on a triangular lattice and analyze the potential of this system for the experimental realization of a supersolid phase. The ground sta…
Universal scaling in a strongly interacting Rydberg gas
Robert Löw, Hendrik Weimer, Ulrich Krohn +5
We study a gas of ultracold atoms resonantly driven into a strongly interacting Rydberg state. The long distance behavior of the spatially frozen effective pseudospin system is det…
